Constituency 2023 Clipped (generalised)

This dataset is the definitive version of the annually released regional council constituency boundaries as at 1 January 2023 as defined by the territorial authorities and/or Local Government Commission, and maintained by Stats NZ (the custodian), clipped to the coastline. This clipped version has been created for cartographic purposes and so does not fully represent the official full extent boundaries. This version contains 58 constituencies, excluding area outside regional council constituency.

​

If a regional council decides to have a Māori constituency, the constituencies within the council are known as general constituencies and Māori constituencies. Constituencies are divisions of regional council areas. They are defined at meshblock level, and do not coincide with the statistical area 1 (SA1) geography or the statistical area 2 (SA2) geography. They are created, based on population, to be the voting areas within councils. Constituencies are required to reflect communities of interest. Their boundaries, so far as is practicable, coincide with those of territorial authorities or wards.

​

The boundaries of constituencies may be reviewed before each three-yearly local government election. Regional councils must review their representation arrangements at least once every six years. The provisions for such reviews are in the Local Government Act 2002.

​

Numbering

Constituencies are numbered based on their corresponding regional council. Each constituency has a unique four-digit code. The first two digits represent the regional council that the constituency lies within. The last two digits are sequential and represent the number of constituencies within a regional council. For example, the West Coast Regional Council (12) contains three constituencies, which are coded 1201, 1202, and 1203.
